Application

Tetrakis(hydroxymethyl)phosphonium chloride solution (80% in H2O) has been used as a reducing agent and stabilizing ligand for the synthesis of gold nanoparticles (AuNPs) from gold(III) chloride trihydrate (HAuCl4.3H2O). It is a tetra-functional, amine-reactive, aqueous crosslinker that can be used for tuning the properties of protein-based hydrogels for 3D cell encapsulation applications.
